What a nightmare! I don't quite remember what happened, but I wiped my mac at some point. And some sequence of events happened that I'm blurry about. But now when I open iTunes, I see most music files have exclamation points. I do have almost all my music files backed up on an external hard drive. Some questions: How do I do a sweep and find all my files that has the exclamation point in mass? I tried to drag and drop from my external hard drive but given that I have 30K of music, it's taking forever... If I finally recreate my files from scratch, how do I retain all my previous ratings/info etc associated with each song? If I have both the exclamation point files as well as the files I dragged over, how do I delete the ones with the exclamation point in mass? Is this even the right approach for my situation? Is there a better way than doing this nightmarish approach?
